Problems solved by technology

However, the operating range of the traditional excavator working device and robot arm is limited by its own structure, and it cannot be multi-stage or even telescopic. Single, complex working conditions and poor terrain adaptability. When the working device is in the recovery state, the end of the working tool sometimes touches the boom cylinder, which damages the boom cylinder and affects the normal operation of the whole machine. In addition, the large-scale operation of the working device is heavy and heavy. Large size, slow driving, difficult transportation, and the working range of small-scale operation working devices is limited

Abstract

The invention belongs to the field of excavator technology and particularly discloses a working device and an excavator. A telescopic bucket rod and a telescopic moving arm in the working device greatly improve the working range of the working device. A four-connecting-rod mechanism greatly improves the rotatable angle of the bucket rod and the working range of the whole working device. A moving arm oil cylinder is placed in a platform and enables the bucket rod to be possibly restored to the lower surface of the moving arm at a large angle, thus, the restoration angle and the restoration range of the working device are improved, and the condition that an operation machine tool scrapes the moving arm oil cylinder in the restoration state of the bucket rod is avoided. The excavator has the large-range operation capacity which a small excavator does not have, has the characteristics, of being light in weight, small in size and flexible, which a large excavator does not have, and is especially suitable for large-area operation by the small excavator or superlarge-area operation occasions of the large excavator. Meanwhile, when the working device is in a completely restored state, the excavator is small in size, light in weight, low in transportation and driving height, and small in rotary radius, and can be driven and transferred easily.

Description

technical field [0001] The invention belongs to the technical field of excavators, and in particular relates to a range-adjustable working device and an excavator equipped with the working device. Background technique [0002] In recent years, large-scale excavators, small excavators and other special-purpose large-scale robots have shown their prowess in various construction and disaster sites, contributing to national infrastructure construction and disaster relief. However, the operating range of the traditional excavator working device and robot arm is limited by its own structure, and it cannot be multi-stage or even telescopic. Single, complex working conditions and poor terrain adaptability. When the working device is in the recovery state, the end of the working tool sometimes touches the boom cylinder, which damages the boom cylinder and affects the normal operation of the whole machine. In addition, the large-scale operation of the working device is heavy and heavy...
